On vient de/du Canada?

It says the answer is du -- but Canada is (f). I thought the rule of venir de/du/des, was feminine de, plural des, masc du. Please help :_

I looked on Wiktionary and the expression ´a l’air livré means out in the open’. When I typed a l’air libre ‘ on the test, the correct answer was a la belle étoile

R.e. this question:

Tous les gosses y vont, mais ________ prend le train.

User "Lolli" in Jan 2018 asked if "personne ne" would also be correct in this sentence (in addition to the "correct" answer of "aucun ne"). I think that in spoken conversation, "personne ne" would be acceptable and convey equivalent meaning. There hasn't yet been a definitive response as to whether "personne ne" is acceptable grammatically. 

Can anyone provide definitive guidance on this? 

(Maybe the kwiziq website logic can't accommodate unanticipated responses?)

If je converts into j' in certain words such as j'aime and j'habite because of the vowels and silent h, then why doesn't nous become nous' in the same words like nous'aime as 'aime' also starts with vowel 'a' before them?
